Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an on-vehicle speaker mounting mechanism, and more particularly to a speaker mounting mechanism suitable for a ceiling-mounted speaker.
[0002]
[Prior art]
An example of a conventional ceiling-mounted in-vehicle speaker mounting mechanism will be described with reference to FIG. Reference numeral 1 shown in FIG. 5B denotes a vehicle-mounted speaker, to which a speaker fixing bracket 2 is fixed. As shown in FIG. 5A, mounting nuts 14 and 14 are welded to the vehicle body 4 in advance.
[0003]
The vehicle body mounting bracket 3 is fastened to the vehicle body 4 by screwing the bolt 6 inserted through the hole of the vehicle body mounting bracket 3 into the nut 14. As shown in FIG. 5 (b), the speaker fixing bracket 2 is fastened to the vehicle body mounting bracket 3 fastened to the vehicle body 4 with bolts 8, and the vehicle-mounted speaker 1 is installed on the ceiling of the vehicle. For safety, both ends of the belt 12 through which the vehicle body mounting bracket 3 and the speaker fixing bracket 2 are inserted are connected by buckles 13.
[0004]
6 and 7 show another example of a conventional ceiling-mounted type on-vehicle speaker mounting mechanism. In this example, the vehicle body mounting bracket 3 is fastened to the vehicle body using the bolts for mounting the assist grip 15 shown in FIG. That is, as shown in FIG. 6B, a part of the cover of the assist grip 15 is raised and the bolt 8 is removed.
[0005]
The assist grip 5 and the vehicle body mounting bracket 3 are fastened together by the bolt 8. Then, as shown in FIG. 7, the speaker fixing bracket 2 is fastened to the vehicle body fixing bracket 3 with bolts 8, and the in-vehicle speaker 1 is installed on the ceiling of the vehicle. For safety, both ends of the belt 12 through which the vehicle body mounting bracket 3 and the speaker fixing bracket 2 are inserted are connected by buckles 13.
[0006]
8 and 9 show still another example of a conventional ceiling-mounted in-vehicle speaker mounting mechanism. In this example, the vehicle body fixing bracket 3 is fixed to the vehicle body by the mounting bolts 18 of the safety belt mounting bracket 16 attached to the vehicle.
[0007]
As shown in FIG. 8, the vehicle body fixing bracket 3 is fastened together with the safety belt bracket 16 by a bolt 18. That is, the bolt 18 inserted through the safety belt bracket 16, the flat washer 20, the vehicle body fixing bracket 3, the flat washer 20, and the spring washer 19 is screwed into the nut fixed to the vehicle body. Since the safety belt bracket 16 has banks 16a and 16a and is locked by the banks 16a and 16a, the vehicle body fixing bracket 3 does not rotate even if fastened with one bolt. The safety belt bracket cover 17 is attached to the safety belt bracket 16.
[0008]
Then, as shown in FIG. 9A, the speaker fixing bracket 2 is fastened to the mounting bracket 3 with bolts 8 and the vehicle-mounted speaker 1 is installed on the ceiling of the vehicle. As shown in FIG. 9B, both ends of the belt 12 through which the belt 12 is inserted through the vehicle body mounting bracket 3 and the speaker fixing bracket 2 are connected by buckles 13 for safety.
[0009]
FIG. 10 shows still another example of a conventional ceiling-mounted in-vehicle speaker mounting mechanism. In this example, bush nuts 24, 24 are driven into two holes provided in the vehicle body in advance as shown in FIG. 10A, and anchor nuts 23 are driven further to secure the mounting portion of the vehicle body mounting bracket 3. Is done.
[0010]
As shown in FIG. 10A, the spacer 22 is inserted into the anchor nut 23, and the machine screw 26 is screwed in a state in which the spacer 26 is prevented from rotating. When the machine screw 21 is screwed in, the leg portion of the anchor nut is opened and the anchor nut 23 is fixed to the vehicle body. Thereafter, the machine screw 21 and the holder 26 are removed, and the vehicle body mounting bracket 3 is fastened to the vehicle body by the tapping screw 25 screwed into the bush nut 24 and the machine screw 21 screwed into the anchor nut 23 as shown in FIG. Worn.
[0011]
Then, as shown in FIG. 10 (b), the speaker fixing bracket 2 is fastened to the vehicle fixing bracket 3 with bolts 8, and the vehicle-mounted speaker 1 is installed on the ceiling of the vehicle. For safety, both ends of the belt 12 through which the vehicle body mounting bracket 3 and the speaker fixing bracket 2 are inserted are connected by buckles 13.
[0012]
[Problems to be solved by the invention]
The above-described conventional vehicle-mounted speaker mounting mechanism shown in FIG. 5 can attach a specific ceiling-mounted speaker only to a vehicle type for which a genuine ceiling-mounted speaker is prepared to be mounted. There was a problem that there was no versatility for stationary speakers.
[0013]
The conventional in-vehicle speaker mounting mechanism shown in FIG. 6 and FIG. 7 has a problem that it is difficult to sit on the rear seat because the space between the head of the person sitting on the rear seat and the speaker is not sufficient.
[0014]
The conventional in-vehicle speaker mounting mechanism shown in FIGS. 8 and 9 is limited to a vehicle type using a specific seat belt, and has a problem that it is not versatile.
[0015]
The conventional in-vehicle speaker mounting mechanism shown in FIG. 10 has a problem that the size of the hole provided in the vehicle body is limited and there is no versatility.
[0016]
As described above, conventional in-vehicle speaker mounting mechanisms have poor versatility, and in many cases, an arbitrary ceiling-mounted speaker cannot be mounted on an arbitrary vehicle type, and even if mounted, the user's request may be satisfied. There was something I couldn't do.
[0017]
The present invention has been made in view of the above points, and the object of the present invention is to be versatile so that any ceiling-mounted speaker can be attached to any vehicle type, and the attachment position is also the user. An object of the present invention is to provide an in-vehicle speaker mounting mechanism that can satisfy the above requirements.
[0018]
